This invention relates to roofing constructions and more particularly toa means for securing the overlapped edges of sheets of roofing materialtogether.

An object of the invention is the provision of a roofing construction inwhich a plurality of sheets of roofing material have their adjacent endsoverlapped for a restricted portion of the width and a narrow bindingstrip formed of roofing material folded upon itself to form a pair ofsuperposed sec:

tions, tacks penetrating the innermost section and the overlapped endsof the sheets of roofing material and likewise a fixed portion of theroof for securing the overlapped ends of the sheets to the roof, theheads of the tacks being located between the superposed sections of thebinding strip with cementitious mate'- rial located between the sectionsfor'securing 539 the sections of the strip together, clips of anysuitable material being employed when necessary for retaining theadjacent edges of the strips in contact with each other.

, This invention will be best understood from a consideration of thefollowing detailed description, in view of the accompanying drawingforming a part of the specification; nevertheless it is to be understoodthat the invention is not confined to the disclosure, 39 beingsusceptible of such changes and modifications which shall define nomaterial departure from the salient features of the invention asexpressed in the appended claims.

Referring more particularly to the drawing, 10 designates a sheathing ofwood which is secured to the rafters of a roof before the sheets 11, 12and 13 are applied. The sheets 11 and 12 have their adjacent edges 14:and 15, respectively, located in overlapped relation while sheets 11 and18 have their adjacent edges 16 -and 17, respectively, located i IlaPPGdrelation The binding strip, shown more particular ly in Fig. 2, andgenerally designated'by the numeral 20, is formed of a narrow strip ofroofing material which is cut, as shown at 21, intermediate thelongitudinal edges of the strip to form sections 22 and 23 which may befolded upon each other, as shown in Figure 1.

The section 22 is secured to either the overlapped. portion 1'? of thesheet 13 or to the overlappedportion 14 of the sheet 11 by 7 means 'ofacement ordinarily used for'the purpose. Tacks 24 are driven through thesection 22 and through the overlapped por tions 16 and 17 and into thesheathing 10 which *is preferably made i of wood... The

heads 25 of the tacks 24 are located between the sections 22 and23 and abinding cement 26 is placed between the sections 22 and 23 for aiding insecuring the sections together and for retaining themin flat contactwith each other. It will be seen by this construction that the heads ofthe tacks are made weatherproof since they are not exposed to theelements.

' U-shaped clips 27 have penetrating prongs 28 forced into the outeredges 29 of the sections 22. The projecting portion of the clip I isbent over the outer-edge 30 of the section 23 and over the outer face ofsaid section. These clips are spaced along the edges of the-foldedsections of the binding strip in fiat contact until the cement securesthe sectionstogether.. y

23 ofeach binding strip will be formed into a unit while the lowersection 22 will likewise be formed intoa unit by the gradualsaturation-of the section-22and the overlapped portion 17 of the sheet17. N V

The clips or U shaped members 27 are formed of soft metal and a're-ofsufficient strength to maintain the edgesof the sections together untilthe cement will form a complete binding for the-sections. If the clipsshould become loosened for any reason, and released fromtheir position,after the 1 cement has securely connected the sections together,suchllooseness would have no effect whatever upon the eflicacy of thestructure. The construction shown in Figures .4 and are substantiallyidentical-with the con- Tstruction shown in Figs. lto 3,except thattheclips 27 are not employed. in. this-case,

o In the construction shown in Figs.- 6 and 7 it will be seen that-twothin strips 35 and 36 are employed which are notbound bya relativelythin edge, as is shown in Figs. 1 In this instance, however; it isnecessary to employ U-shaped clips 27 and 27* atthe opp-ositetedgesofthe strips for aiding in retaining the strips in flat contact with.each' otherwhile the cement binder has become suflicientlyset to retainthe sections together.
